Question 303676: Hello,
If someone could help me solve for this problem from, the Book: Intermediate Algebra by Mark Dugopolski, I would greatly appreciate it.
Evaluate each expression using a = - 1, b = 2, and c = - 3
(a - c)(a + c)
{I was thinking: -1 - -3 * -1 + -3 (4 * -4 = Answer: -16) Is this correct?}
Please let me know
Thank you

----------------
Substitute
You must do the operations inside the parenthesis first.
